Take the lens off and push from underneath on the wind on side. Should come out easy. If stuck and upside down it may be jammed in. Still try to push up very gingerly. Not sure what else you can do. Domed clear glass should be above the frosted glass.
Didn't realise the head was still on.
There's a silver button on the back of the camera, push that and it should release the view finder head.
May require a little force if it hasn't been used for awhile.
Push the VF release button on the back of the camera. Really firmly. This also retracts the two little pins at the left side that hold the focusing screen in place. If you can press hard enough to get the pins to retract all the way, the screen should fall out when you turn the camera body upside down.

See those two little angled cutouts in the screen's metal frame? The two retracting pins fit in there. So the words "Nikon F" go toward the front of the camera with the cutouts on the left (rewind) side. Just drop the screen in and press the VF release button and it should drop into place.
